JosErH ANTHONY SGHLEHR, or noa'rnvrrnn, soirrrr DAKOTA.

To all whom it may. concern 1 Beit known that I, J OSEPH A. SCHLEHR, a citizen of the United States residing at Northville, in the county of Spmk and State of South Dakota, have invented certain new and useful Improvementsin' Pliers and End Wrenches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in. open-ended tools such as pliers and wrenches, and my object is to provide a tool of this character in which both jaws are narrowed to a point at their front ends, and in which. the opposite sides of said jaws converge to said point, one of said sides extendingin the same direction as to length of the tool, while the other side is oblique with respect to such length. By this arrangement, I provide a tool which will work to equal advantagewhen used at right angles to the work or in diagonal or oblique relation therewith, and one which will be highly efficient and desirable when working in cramped quarters. When constructing pliers in the manner set forth, they may be used to great advantage for removing cotter pins or the like and for more effectively holding numerous small articles than is possible with pliers of ordinary construction;

With the foregoing in view, the invention resides in the novel shaping of the jaws as in Fig. 1.

i the hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing.

Figure 1 is a side elevation of a pair of pliers embodying my improvements.

Fig. 2 is an edge view of the pliers shown Fig. 3 is an inner edge view of one jaw of liers.

Figs. 4 and 5 are respectively side and edge views of an end wrench constructed in accordance with the invention.

Both jaws 3 are narrowed to a point 4 at their ends, and the opposite sides 5 and 6 of said jaws are flat throughout their areas I55.

the tool as usual.

By the features of construction above described, the pliers may be used either at right angles to the work or oblique with respect thereto and are of great advantage in picking up small pins and the like from flat surfaces, in removing cotter pins, workmg 1n all sorts of cramped quarters, andin fact are of general utility, particularly in the repairing of automobiles. The device has been given rigid tests by a number of automobile mechanics and has proven in all cases to be much more advantageous than the common forms of pliers, due to its universal adaptation for all purposes.

In-Figs. 4 and 5, I have shown an end wrench having different size jaws 3 at both ends. All of these jaws are narrowed to points 4 at their front ends and the opposite sides 5 and 6 of said jaws are flat throughout their areas and converge to said points, the side 5 of each jaw extending in the same direction as the length of the tool, while the side 6 is oblique to such length.

The closed ends of the nut receiving notches 8 between the jaws 3, preferably are disposed at right angles to the jaw sides 6* as shown most clearly in Fig. 5.

By constructing wrenches of numerous types in approximately the manner set forth, they may be used either at right angles to the nut axis, or oblique to such axis as occasion may dictate, and in the latter instance there is no dangerof mutilating the nut or of the-wrench slipping therefrom, as now commonly occurs when the ordinary end wrench is used at an angle other than a right angle to the nut axis.

Wrenches constructed in accordance with the invention have been used with great success by automobile repairmen and have been found in all cases to be much more, efficient and desirable than the ordinary end wrenches now in use.

Excellent results are obtainable from the of the invention as claimed, numerous of the tool, while the side 6 is oblique to changes in form, proportion and other minor details may well be made.

I claim:

1. An open-ended nut gripping andturning tool comprising a pair of handle-carried jaws, narrowed substantially to points at their front ends, the opposed sides of said jaws being fiat throughout their areas and converging forwardly with respect to each other, one of said flat sides extending in the same direction as the length of the tool, the other flat side being oblique to such length. 2. A. air of pliers for gripping and turning nuts, rods and other machine parts, comprising two jaws narrowed to points at their front; ends, the opposite sides of said jaws being flat throughout their areas and converging forwardly to said points, one of said flat sides extending in the same direction as the length of the tool while the other flat side is oblique to said length, said jaws having teeth on their inner edges extending at right angles to said oblique flat side.

3. A structure as specified in claim 2, said inner edges oi the aws also having opposed transverse grooves contiguous to said points to provide a claw-like formation for insertingand removing cotter pins and the like.

. In testimony whereof I have hereunto set my hand.

JOSEPH ANTHONY SCHLEHR.
